Product details

It uses screw-type terminals and is rated for a maximum of 10 A, with specific current ratings defined per voltage level — 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 6 A at 250 V, and 3 A at 400 V, among others. For AC-15 duty, it carries 10 A at 24 V, 4.7 A at 60 V, 3 A at 110 V, 1.2 A at 220 V, 0.5 A at 440 V, and 0.26 A at 600 V.

Mounting and fit

Snap-on mounting means this block clips directly onto the front of the contactor or contactor relay without tools — no additional DIN-rail space consumed. Dimensions are 36 mm wide, 37.5 mm high, and 43.7 mm deep, so it adds minimal depth to the assembly. The IP20 protection on the front is standard for enclosed panels; keep it behind a cabinet door or cover.

Contact configuration and ratings

The switch provides one leading NO contact and one lagging NC contact, meaning the NO closes before the NC opens during actuation — important for sequencing in safety or interlock circuits.

Frequently asked questions

How do I get current pricing and availability for 3RH2911-1FB11-ZX95?

Submit an RFQ through this listing. We source the part to order through independent distribution and confirm pricing and availability at quote time — no automated stock figures here.

Will 3RH2911-1FB11-ZX95 drop into a panel specified around 3RT5056-8AP38-0PR0 without rewiring?

No — the 3RT5056-8AP38-0PR0 is a power contactor, not an auxiliary switch block. The 3RH2911-1FB11-ZX95 is designed to snap onto the front of 3RT2 contactors and 3RH2 contactor relays, not to replace a power contactor. If your panel uses a 3RT5-series contactor, verify the interface compatibility; the 3RH2/3RT2 family is the intended host.

What compliance documentation does Siemens provide for 3RH2911-1FB11-ZX95?

As a SIRIUS component, it carries CE marking for the European market. Specific RoHS, REACH, and UL documentation is available from Siemens on request; the product is designed to meet applicable industrial control standards.
